Asked by Jul 25, 2016 at 11:45 PM about the 1991 Chevrolet Blazer 4WD

Question type: Maintenance & Repair

I was replacing the fuel pump on my 91 blazer, and
there is a loose black wire hanging. It turns into
brown wire, and goes into a rubber collar with the
grey and purple wires to the fuel pump. The 2
grounds to the fuel pump are grounded. I have no
clue what this wire is. Any help is appreciated
